Docs: Missing documentation for wallet type initialization delay

[danielapolkasu0619-rgb]

The security docs mention wallet isolation but don't document the initialization delay after deploy.

Users experiencing Unsupported wallet type: eoa errors need guidance on:

1. Expected initialization time after deploy
2. How to verify delegation status
3. Retry strategy for API calls during initialization

Related issues:

• Agent deploy fails with 'unsupported wallet type' on Base mainnet clawk#1 (full reproduction: https://htmlpreview.github.io/?https://gist.githubusercontent.com/danielapolkasu0619-rgb/7b253d252ece1bccab681fdd41a87390/raw/csrf_final.html)
• tokenpage/yieldseeker-contracts (factory mismatch)

This is causing confusion for developers building on the platform.
